The push-pull and rotation functions adopt a dual closed-loop hydraulic system. Compared with conventional hydraulic systems, it delivers over 20% higher working efficiency, approximately 50% less heat generation, and more than 20% energy savings.
Powered by a Cummins engine dedicated to construction machinery, it offers outstanding energy efficiency, environmental friendliness, high performance and robust power output.
